The 'occult' is canon within the L&C universe, beginning with
All Shook Up. - Jimmy and Clark visited a psychic who sensed 'Superman's' aura. Luthor planned to use soul/mind transfers to evade justice and Woody Samms made a habit of it. Wells had a Soul Tracer and Lois and Clark had previous incarnations (including a curse). Baron Sunday attacked Clark magically.
BTW, for those who want to know Komack's story about what happened in Ireland it's at
Midsummer's Eve
